Hi Steve,

Pretty much all you want is taken care of by these excellent projects:

http://www.öpnvkarte.de/ (that's Alt-Gr+[, then o, on my keyboard :-) )
http://wiki.openstreetmap.org/wiki/User:Colin_Marquardt/Hike_%26_Bike_Map
http://www.openpistemap.org

The second one is a biking map that's fully open source, so that would
be a good place to start.

Cheers,
Andy
